Whales – Conservation of Bio-diversity is Key for our Survival.

Evolution of the global bio-diversity and the social life in natural eco-systems around us has long-standing histories. Yet our knowledge is not complete and many secrets remain to be mostly unknown.

Sperm whales are the most hunted species, then for generations it took a great many men to kill few whales but the technology has now reversed the problem. The problem before was to find sperm whales and kill them, but the problem now is to find how many sperm whales than can be killed without endangering the species. In a world full of hunger production doesn’t slow down for science, the only means to find out the proper answers. The ultimate fate of the whales and the industry depends on the accuracy of science to shape sustainable management policies in an ever-increasing complexity and fragmentation of “industry-society” sectors.

Sperm whales have the largest brain of any animal and probably dive deeper than many other mammals. We know little about why they sing, we even don’t know how, how much they sleep and even if they need to sleep at all. They have complex social life of which we know very little about.

Biologists collect much raw material for the construction of their re-productive cycle. In which, the age of the whales are key component to follow the biology and ecology of whale populations. Sperm whale carries its life calendar in their teeth. Teeth, in this context, are true age-indicators of the whales as they consist of alternating “drack-light” layers. When the age is known, it is then correlated with other information from the soft parts of whales and by computer simulation (size, range and reproductive capacity for various whale populations) knowledge on, how many whales can be safely harvested, can be gained. Biologists make the statistics but the whaling industry take care of the rest.

In a separate “POST” we will tell more about the threats facing “pilot whales”
